UNITED STATES WILLIAM J. LEACI-I, OF BURLINGTON, wisoonsrnf TWISTING .DEVICE.

Application filed March 23, 1928. Serial No. 264,079.

My invention relates to improvements in twisting devices, and it consists in the combinations, constructions, and arrangements herein described and claimed. r

An object of my invention is toprovide a twisting devicein which certain improvements are embodied over the device disclosed irgggly Patent No. 1,629,800, issued'May 24, 1- I .o

' A further object is to provide a twisting device which is easy tooperate'inthatathe device may be conveniently opened with one hand A further object is to provide a twisting device in which thebody portion is designed in two parts, one of the parts being pivotally mounted with respect to the other, and in which the sockets forreceiving the handles of the device are provided in the part supporting the pivotally mounted part, thereby providing a twisting device which is relatively durable and simple in construction.

A further object is to provide a twisting device in which the number of hinges is reduced to a minimum.

A further object is to provide a twisting device which is rigid, thereby providing a twisting of a tube.

, and a section 2 pivotally mounted at 3 upon device which isconvenient to handle.

A further object is to provide a twistlng device in which removable dies are provided,

and in which the diesare effectively sup-' ported in the twisting deviceso that a maximum amount of power may be applied to the device. a

Other objects and advantages will appear in the following specification, and thenovel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a side elevation of my device,

The sections 12 and 13 arehingedly I cured together .at15, as shown in Figure 4,

and may be opened up, as shown. The section 12 is provided with-a tongue 16 which is arranged to pass into a recess 17 in the section groove 11,

13 when the two sections are closed, as shown in Figure-1. When in the closed position, the tongue 16 is locked within the recess 17 by means of a spring-pressed pin18 which passes through an opening 19 in the tongue.

The ratchet mechanism comprising the sections 12 and 13 is adapted tosupporta die 20 which is made in two parts. In referring to Figure 3, it will be noted that the die 20 is somewhat thinner than the sections 12 and 13 so that grooves 21 may be provided in the latter for supporting the die. The sections of the die 20 are removably supported in the grooves 21. When the sections of the die 20 are disposed in the grooves 21, as shown in Figure 1, the sections are retained in position.

by means of spring-pressed ball members 22. Suitable recesses are provided lnthe die 20 for receiving a portion of the ball members 22.

The body portion A may be rotated in one direction'about the ratchet mechanism, but is locked against rotation with respect to the ratchet mechanism when rotated in the opposite direction Means for locking thelbody portion A against rotation with respect to the ratchet mechanism consists of a. springpress ed pawl 23, as shown in Figure 1. The die 20 is provided with intersecting openmgs 24 through which a tube 25 containing cables 26 may be disposed. I

From the foregoing descript on of the vatate in one direction step by step.

rious parts of the device, the operation thereof may be readily understood. In Figure 6, I have shown a pair of twisting devices B and C mounted upon the tube 25. hen the .body

p'ortion A is mounted upon the tube 25, the

upon the tube twister may be applied to the tube 25. After the twisting device has been applied to the tube, the ratchet mechanism is closed and locked by means of the pin 18 and the section 2 is moved down upon the ratchet mechanism and locked by moving the locking device 8. I

It will be'noted that a slight rotation of the handles about the transverse axis of the device w'ill'cause the ratchetmechanism to ro- Thus it will be seen that I have provided a twisting device which. may be effectively used for twisting a tube that is disposed relatively near a second tube or cable. WVhen twisting the tube 25, a pair of devices is employed, as shown in Figure 6. The individual devices when so mounted will be rotated in opposite directions, or one of the devices may be held stationary and the other rotated.

The present invention provides a device whichis convenient to handle, particularly when working in inconvenient places. The body portion of the device is rigid and the device can be opened with one hand. Further than this, I have provided a device in which the die may be easily removed without the use of screw drivers and the like. The die may be quickly changed for other dies and when: the die is disposed in place, it is firmly secured. The spring-pressed ball members 22 ymrmit the two sections of the die 20 to be pulled out by the hand.
